Relatively speaking though. Just as you would afford 100 metre runners over the decades allowances because of the developments and improvements, same goes with boxers. Anyone with eyes can see there is nobody talented out there except him.

The difference with boxing, and with the likes of tennis, is your opponent directly influences your performance. Consistently fight someone average, and you're not going to be troubled. You're going to look better than if you had someone closer to your level.

Lewis would be in amongst it, as some of the more routine fighters he took on were easily a level above Usyk's opponents. Prime Tyson too and the 70's Three musketeers. Hard to know, but quality of opposition needs to be a bigger factor than technological and sports science advancements, as they only relate to comparisons with the past.
